The Prophet is more worthy of the believers than themselves. [Al-Ahzaab. Ayah:6]

Summarised benefits:

The closest thing a person possesses and the most important thing he has is himself (herself). However, the Messenger (sallal-laahu-alayhi-wasallam) is more worthy of a person than himself (herself). That is because the Messenger (sallal-laahu-alayhi-wasallam) gave them (i.e. the creation) sincere advise, and showed them affection and compassion. There is none who showed the most mercy and compassion to the creation besides the Messenger, for he is the greatest favour amongst the creation to the people than everyone else. That is because neither an atom’s weight of good has reached them nor an atom’s weight of evil is repelled from them, except through him [i.e. due to the message he (sallal-laahu-alayhi-wasallam) conveyed to them from Allaah]. And for this reason it is obligated on them that when the desires of their souls are in opposition to what the Messenger wants (from them), they should give precedence to what the Messenger wants (from them). They should not oppose the statement of the Messenger (sallal-laahu-alayhi-wasallam) with the statement of anyone else-regardless who that person may be. And they are to sacrifice themselves, their wealth and offspring in giving precedence to loving the Messenger (sallal-laahu-alayhi-wasallam) over the entire creation. They are not to say anything (i.e. in the religion) until he says so, nor do they put themselves forward before him.
